Stationary Hydrosieve, Static Wastewater Screen, Manufacturer

The stationary hydrosieve, also widely known as a static wastewater screen or a sieve bend screen, is the most trusted and simple solution for liquid-solid separation in wastewater treatment fields.

This non-powered equipment plays a critical role in pre-treatment, effectively removing solids to protect downstream systems and improve overall process performance.

The Science Behind the Static Screen

A stationary hydrosieve operates on a simple, yet highly effective principle based on the Coandă effect. The unit consists of a curved, parabolic screen, typically constructed from durable stainless steel. This curved screen features a series of triangular or V-shaped wedge wires. As wastewater or process fluid flows over the inclined surface, the liquid adheres to the curved screen bars due to surface tension and the velocity of the flow.

The design creates a controlled hydraulic action:

• Deceleration of Screenings: The curve of the screen slows the solids, allowing them to tumble and dewater.

• Efficient Drainage: The liquid passes through the precise, narrow slots between the wedge wires.

• Self-Cleaning: The unique shape of the wedge wires and the continuous flow of solids prevent clogging, ensuring the screen remains efficient with minimal maintenance.

Because they have no moving parts, these static screens are energy-efficient and quiet, making them a cost-effective alternative to mechanical screens.

Key Applications Across Industries

The versatility of stationary hydrosieves makes them invaluable in a wide range of applications for both municipal and industrial wastewater treatment.

• Food and Beverage Processing: From slaughterhouses and dairies to fruit and vegetable canning, these screens are essential for separating food waste, such as peels, seeds, and stems, from process water. This allows for the recovery of valuable products and reduces the biological load on subsequent treatment stages.

• Pulp and Paper Mills: They effectively screen out fibrous materials and other solids, which is critical for maintaining equipment and preventing blockages.

• Industrial Effluents: Used as a primary treatment step in industries like textiles and mining to reduce suspended solids before they enter the main treatment process.

• Municipal Wastewater: They serve as an excellent first stage in pre-treatment to remove large debris like rags and plastics, protecting pumps and other sensitive equipment in the headworks of a plant.

Choosing the Right Manufacturer

When selecting a stationary hydrosieve, partnering with a reputable manufacturer or supplier is crucial. A quality hydrosieve is defined by its robust construction, precise engineering, and the ability to customize its design for specific applications.

Key factors to consider include:

• Material: Ensure the screen and frame are made from high-grade stainless steel (like AISI 304 or 316) for corrosion resistance.

• Screen Fineness: The sieve opening size is a critical factor, ranging from very fine to coarse, depending on the type of solids being screened.

• Flow Capacity: The unit must be appropriately sized to handle the required flow rate for your application.

• Manufacturer Expertise: Choose a fabricator with proven experience in wastewater solutions to ensure the equipment meets your specific needs and performance standards.
